T0 aZZ whom it may concern:

Be it known that we, JOHN T. LYNoH and EDWARD J. FITZGERALD, of Holyoke,in the county of Hampden and Commonwealth of Massachusetts, haveinvented a new and useful Improvement in Liquid-Discharging Apparatus,of which the following is a specification, reference being bad to theaccompanying drawings, forming part thereof.

Our invention relates to that class of devices for discharging liquidsfrom a receptacle in which one member is permanently secured to thereceptacle, normally closing the outlet thereto, and a second member isadapted to be affixed to said first member and to co-operate with it insuch manner as to open the outlet and discharge the liquid.

The'object of our invention is to provide an apparatus of this nature inwhich the first member can be readily secured to the receptacle by beinginserted from the outside through the faucet-hole or other outletthereto, and in which locking devices are employed to supplement theaction of the usual spring to normally close the outlet. To this end ourinvention consists in the construction and combination of partshereinafter fully described, and particularly pointed out in the claims.

' Referring to the drawings, in which like letters designate like partsin the several figures, Figure 1 is a side elevation of one member ofthe apparatus invented by us as permanently afiixed to aliquid-receptacle. Fig. 2 is a vertical longitudinal section thereof.Fig. 3 is a perspective view showing the parts constituting said memberseparately and also assembled preparatory to being affixed to thereceptacle. Fig. 4 is a vertical longitudinal section of thecompleteapparatus as applied 0 a receptacle when discharging liquid thererom.

Proceeding first to describe the member of our apparatus which isdesigned to be permanently alfixed to a receptacle, the letter Odesignates a bushing, made of brass or other suitable material, havingthe flange D at one end, and preferably screw-threaded upon itsperiphery, as shown, whereby it is adapted to be screwed into thefaucet-hole or other outlet to a liquid-receptacle, a section of thewall 1, 2, and 4. The bore of said bushing is also screw-threaded for ashort distance from its outer end, to adapt it to receive the secondmember of the apparatus, as hereinafter described.

Projecting from the inner end of the bush ing, and preferably madeintegral therewith, as shown, are two parallel rods, L, and secured tothe ends of said rods by rivets m, or in other suitable manner, is abar, M, said rods and bar thus forming a bracket for supporting andguiding the stem H of a valve-plug, G,which stem passes freely throughan orifice, h, in said bar. The plug G is of proper diameter to closelyfit the inner end of the bore of the bushing, said plug and the mouth ofthe bore being preferably made slightly tapering, as shown, to insure aperfectly-tight joint.

A spring, I, surrounding stem H, will normally retain plug G within themouth of the bore to prevent the escape of liquid from the receptacle,and also to prevent the latter from becoming fouled, when empty, by theentrance of dust and other impurities through the outlet. In order tosupplement this action of the spring, and positively retain the plug inboth its open and closed positions, we have added to this member of theapparatus a locking device,which, as shown in the drawings, consists ofa crossbar, K, rigidly secured at the middle point thereof to stem H.The ends of said bar extend slightly beyond the rods L of the bracketand upon opposite sides thereof, and saidrods are provided with notchesN 0 upon the side adjacent to the contiguous end of the bar, saidnotches N being opposite the ends of the bar when the valve is open, asshown in Fig. 4., and notches 0 being opposite said ends when the valveis closed, as shown in Figs. 2 and 3. The spring Ihas one of its endsinserted in a hole, 1', in the barM of the bracket, and its other endconnected to the cross-bar Knpon one side of stemH in such manner thatit exerts an axial strain upon the stem to press the ends of thecrossbar against rods L in addition to its function of pressing saidstem and the plug toward the bushing. From this construction it followsthat the plug will be securely locked in both its open and closedpositions by thebar K as ICO its ends are forced by the stress of thespring into notches N and 0, respectively, and that a slight axialmovement of said plug in opposition to the stress of the spring willrelease said bar from the notches, so that the valve can be opened bypushing back the plug against the lengthwise pressure of the spring, or,when open, can be closed by said spring automatically.

The plug G will be provided on its outer face with means for engaging akey therewith, for imparting thereto the slight axial movement abovereferred to, and in this instance such means are shown as consisting ofa central rectangular depression,

The bushing will preferably be provided with a cover or seal, E, at itsouter end, pivoted thereto by screw 0, which, when closed, as shown inFigs. 1, 2, and 3, will prevent en trance to the bore thereof of dirtand impurities of any sort, which would otherwise be likely to clog theinterior screw-threads and to foul said bore. \Ve prefer, also, tosecure a screen, F, of fine wiregauze to the inner end of the bushinginclosing the bracket, as shown, to prevent sediment in the liquid fromchoking the valve or passing out therethrough.

As previously stated, the parts thus far dc scribed, constituting thefirst member of our apparatus, are designed to be permanently secured tothe receptacle, and as the bracket and screen, secured to the inner endof the bushing, do not extend beyond the line of the periphery of thebushing, the parts can be assembled, as shown in Fig. 3, and can then beinserted in the faucet-hole or other outlet to the receptacle, beingsecurely held in place by the bushing itself. This feature of ourinvention is of especial importance in applying the apparatus toreceptacles already in use, since it renders opening the receptaclewholly unnecessary; and it is also of great importance when it isdesired to remove the portion of the apparatus lying within thereceptacle for the purpose of renewing the spring or making otherrepairs, which can be done by simply unscrewing the bushing.

The second member of our apparatus, as shown in Fig. 4, consists of theshell P, having a central chamber, and an outlet-stem, X, leadingtherefrom, having the valve V. The shell is provided at one end with thescrewthreaded nipple V, whereby it is adapted to be connected to theouter end of bushing C, as shown, and at its opposite end said shellsupports and guides a key, Q, which passes longitudinally therethrough.The key is provided at its outer end with a hand-wheel, R, andterminates at its inner end in a rectangular point of a size to fiteasily in the depression 9 in the face of plug G. Lugs U upon the keynear its inner end prevent it from being accidentally withdrawn from theshell. The bore of the shell from its inner end to the central chambertherein is of such diameter that free passage for the liquid around thekey is afforded, while from the chamber to the outer end of the shellsaid bore is reduced in diameter to closely embrace the key, and thusforms a bearing in which the latter is capable of being movedlongitudinally and axially. A packing box, S, prevents the escape ofliquid from the outer end of the shell.

The operation of theapparatus is as follows: The first member beingaffixed to the receptacle with its valve closed, as shown in Figs. 1 and2, will effectually prevent the entrance thereto of all impurities, itsaction in this respect being assisted by the closed seal E. The valvewill also prevent the escape of the liquid B from the receptacle whenthe latteris filled; and being securely locked by the cross-bar restingin notches 0, no amount of jar lnCldent to handling and transporting thereceptacle can loosen plug G in its seat in the mouth of the bore of thebushing. For the same reason, the intentional opening of the valve byunauthorized persons is rendered difficult as compared with suchapparatus as heretofore constructed, in which it is necessary merely toforce back the plug to gain access to the contents of the receptacle.\Vhen it is desired to discharge the liquid,sca1 E is swung back, asshown in Fig. ft, and the nipple V of the second member 1s screwed intothe outer end of the bore of the bushing, the valve V being closed. Thekey is then advanced and slightly rotated, if necessary, by means of itshand-wheel R until its squared end T enters depression g in the plug,and, after turning the plug and its stem sufficiently to release thecross-bar from notches O, the key is again advanced, pushing back theplug until the ends of the cross-bar are forced into notches N by thestress of spring I, thus locking the valvein its open position.Theliquid is then free to flow through the shell P and its stem X, andcan be .discharged in the desired quantities by opening and closingvalve XV, as with an ordinary faucet. Then all the liquid has beendischarged, or when, for any reason, it is desired to remove the secondmember before the receptacle is emptied, a slight rotation of plug G, bymeans of the key, will release the cross-bar from notches N and permitthe spring to close and lock the valve, as before.

It is obvious that an operative device could be constructed to lock thevalve in which the bar K would project from but one side of the stem Hand contact with but one of the rods L; but we prefer to make it asshown, as be ing the stronger construction.

It is also obvious that the engagement be.- tween the end of the key andface of the plug to impart axial movement to the latter could beeffected in ways other than that shown within the spirit of ourinvention. \Ve therefore do not wish to limit ourselves to the exactconstruction shown in all of its details, as various modificationsthereof could be made without departing from the essence of ourinvention.
